ENSlLAGE-CUTTING -MACH|NE.

SPECIFICATION forming part of Letters Patent No. 341,309, dated May 4, 1886,

To aZZ whom it may concern.-

Be it known that we, JOHN M. BAILEY, of Waverly, in the county of Sussex and State of Virginia, and PEMBROKE S. RIoH and JOEL GARFIELD, both of WVorcester, in the county of Worcester and State of Massachusetts, as

joint inventors, haveinvented anew and useful Improvement in Ensilagc-Outting Machines, of which the following is a specification.

Our invention relates to certain improvements in that class of cuttingmachines in which the cornstalks to be out are fed between feed-rollers provided for the purpose v and cut into. short pieces by knives fastened upon the arms of a revolving balance-wheel; and the novelty consists in the construction, arrangement, and adaptation of the parts, which will be more fully hereinafter set forth, and specifically pointed out in the claims.

In the accompanying drawings, in which similar letters of reference indicate like parts. Figurel represents a full top view of our whole machine. Fig. 2 represents a front or end view of the same. Fig. 3 represents a partial side view of the machine, showing one side of the head and the mechanism for communicating motion to the lower feed-roller. Fig. 4 is a sectional view taken lengthwise of the machinejust outside of the hopper-head B, and shows the mannerof weighting the upper feed-roller. Fig. 5 represents the other side of the head of the hopper from Fig. 3, and

shows the gearing communicating motion from the lower to the upper feed-roller. Fig. 5 6 is a partial View showing a section of one arm of the revolving balance-wheel, the revolving knife 70, and the manner of bolting the knife is to the arm to secure the proper adj ustment of the revolving knives.

A represents the main frame of the machine.

0 represents the hopper or trough into which the forage to be out is placed.

B represents the castings which form the sides of the head or end of the trough, and to 5 which the feed-rolls, gearing, and stationary bed-knife are secured.

The corn or forage to be cut is fed between feed-rollers R R. The feed-roller R revolves in stationary boxes placed in the head-pieces B B. The feed-roller R revolves in boxes formed in levers Z Z on each side of the ma- (No model.)

chine. Said levers l are pivoted to the head B at pivot 0, allowing the roller R to rise or fall in the arc of a circle having its center at the pivot 0. The levers Z Z project upward on each side of the feed-roller R, and support a cover, it, protecting the upper roller, R, and assisting to guide the corn or forage between the feed-rollers. The connecting guard-cover i can be attached rigidly to the levers Z Z, or a flexible connection can be used to allow the feed-roller R to vary its position to accom modate more or less depth of forage at one end of therollers than at the other.

12 is a shaft revolving in boxes secured to the 6 5 main frame. (See Fig. l.)

P is a drivingpulley secured to the shaftp.

D is a large heavy balancewheel mounted on the revolving shaft p. The balance-wheel D is provided with arms, as shown in Fig. 2, three arms being there represented; but more or less maybe used, as may be desired. Upon each arm a steel knife, 70, is secured by bolts 0 c, and the knives k k, revolving with the arms of the balance-wheel, cut the cornstalks or forage into short sections as the cornstalks or forage is fed over the bed-knife In? by means of the feed-rollers R R.

k is the stationary bed-knife, as shown in Figs. 1 and 2, against the edge of which the So revolving knives in shear off the forage as it is fed over said bed-knife by the feed-rollers.

It is of great importance that the revolving cutter-knives 7t It should pass close up to the edge of the bed-knife It. Any endwise play of the shaft p would allow the revolving knives to spring away from the stationary bedknife, and would interfere with the proper operation of the knives.

To avoid all endwise play of the shaft p, we 0 provide a set-screw, s, secured to the main frame A by a support, a, as shown in Fig. 3. The box I), in which the shaft 1) revolves, is adjusted on the frame by means of the setscrew 8, and is held in position by the bolts d. If the shoulder upon the shaft p or the end of the box I) should wear, so as to allow any end-play to the shaft p, it can be easily tightened by turning up the set-screw s, and the revolving knives can be thus adjusted to the too bed-knife and easily and permanently kept in their true position to secure a good shearing out upon the edge of the stationary bed-knife 7c. The knives k are each adjusted on the arms of the balance-wheel D by means of the bolts 0 and set-screws a, (see Figs. 2 and 6,) so that all the knives 7c can be perfectly adjusted to the bed-knife to secure a shearing out when the balance-wheel revolves. Motion is communicated to the lower feed-roller, R, by means of the dial-plate J, (see Fig. 3,) said dial being provided with cogs jj, into which the screw-gear S meshes. The screw-gear S is placed loosely upon the shaft 1), and is driven by the clutchsleeve 0, which is operated by a lever, d. When the clutch-sleeve c engages the catch 0 on the end of the screwgear, the screw-gear revolves and the dial-plate J communicates motion to the feed-roller R Coarse or finerscrews S are used, as it is desired to secure a longer or shorter out upon the forage. The screw S is made in halves, so that it can be removed and another replaced upon the revolving shaft 1) to alter the length of cut. By means of the handle (1 the feed-motion can be instantly started or thrown out of gear. Motion is communicated from the lower feed roller, R", to the upper feedroller, R, by means of the train of gears g g g 9 upon the other side of the feed-rollers from the dial plate J, as shown in Fig. 5. The upper feed-roller, R, is designed to rise and fall as the amount of forage to be cut varies in depth. The position of the gear. 9 is fixed, as the shaft connecting it to the lower feed-roller revolves in fixed and stationary boxes. The gears g, g, and are attached to a frame, m 0c 00. A link, a, connects the centers of the gears y and g. The gears g and g are free to rise and fall as the feed-roller R is raised or lowered by the different depths of forage passing between the feed-rollers; but the feedgears g, g", g, and y will always retain their proper relative position to each other and follow the movable feed-roller R, in whatever position it may be, allowing it to rise and fall freely to accommodate any desired depth of forage to pass between the feedrollers. Two frame-links, x :v w, are used, one on each side ofthe fecd'gearsg, g and g, and short studs pass through the gears g connecting the frame-links and forming bearings upon which these gears revolve. The links 00 on each side of the gears g g are connected in a similar manner.

As shown in Fig. 1, the bevel-gearp on the shaft 19 meshes into the bevel-gear 0 on the shaft 0 Both shafts p and 0? turn in a box, at 12, secured to the main frame.

I is a handcrank attached to the shaft 0 and, if desired, the machine can be run by hand for light work by it. The operator can turn the crank with his right hand, and the short shaft 0 and handcrank I, as shown in Fig. 1, are placed in such a position in relation to the hopper that the operator can use his left hand to hold or adjust the forage to be run through the cutters, and this machine can, if desired, be conveniently used as a handmachine for cutting any kind of forage.

By the above-described arrangement of the shafting and gears in our machine, the driving-pulley P can be attached either to the shaft 1) or to the shaft 0", in place of the hand crank I. Thus the driving-belt can be applied to drive the machine in front or upon the side of the machine, and in whichever direction may be most convenient in actual operation, as the line ofthe pulleys, on the shafts p and 0 are at right angles to each other.

We have shown and described a complete machine; but it will be understood that we lay no claim to the combination, with a stationary knife on the throat of the feed-box, of a shaft carrying a flywheel provided with knives, the adjustable journal-box, and the screws to force said box against the hub of the fly-wheel, whereby the knives carried by the latter are adjusted to take up wear.

Having thus described the nature and operation of our improved ensilage-machine, what we claim as new, and desire to secure by Letters Patent, is-

1. In an ensilage-cutting machine, the combnation, with the lower roller, R and the upper roller, R, connected at one end by gears and a frame and link, as shown, the former roller having upon its opposite end a disk, J, with teeth j, of the removable and interchangeable worm S, hung loosely upon the shaft p, which carries the fly and cutter wheel, the clutch c, and lever d,whereby the condition offeed may be regulated and the feed thrown into or out of action at will, as set forth.

2. In an ensilage-cutting machine as described, the combination of the lower roller, R its connections with the main shaft, and a clutch mechanism for throwing it into or out of gear at will, of the upper roller, R, hung movably in pivoted elbow-lever Z, and having gear 9, the gear 9, rigid with the lower roller, R, and connected with the gear 9 by the gears g g, the frame 00 00 x, and link a, all arranged and operating as set forth.
